JOHN M. SORLIE, OF EAU CLAIRE, WISCONSIN.

WINDOW-SHADE FASTENER.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed June 3, 1912. Serial No. 701,168.

To all whom it may concern Be it known that I, JOHN M. SoRLm, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of \Visconsin, have invented certain new and useful Improvements in WVindow- Shade Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved window shade fastener, especially adapted for use in cars, and to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings,Fignre 1 is a view in elevation showing a portion of the inside of a car, having applied to one of its window frames and an attached window shade, one of my improved window shade fasteners; Fig. 2 is a detail view, on an enlarged scale, of a portion of my improved window shade fastener, partly in elevation and partly in vertical section; Fig. 3 is a detail view, partly in vertical section taken on the line m m of Fig. 2; and Fig. 4 is a horizontal section taken 0n the line m :0 of Fig. 2.

Of the parts of the car necessary to show the improved window shade fastener applied in working position, the numeral 1 indicates the car body; the numeral 2, the window casings; and the numeral 3, the windows. In front of one of the windows 3, is hung a window shade 4 tacked or otherwise secured, at its upper horizontal edge, to a spring wound roller 5 of the standard or any desired construction. The ends of the roller 5 are mounted in the customary pair of in wardly projecting supporting brackets 6 secured to the window casings 2, at the top of the window 3.

For guiding the window shade 4 for true vertical movement, while the same is being raised and lowered, I telescope a tubular bar 7 through a horizontally extended hem formed in the window shade near its free end. The bar 7 is of such length as to project slightly beyond the vertical edge of the window shade 4. On each end of the bar 7 is rigidly secured, at its intermediate portion, a guide head 9. These guide heads 9 are in the form of vertically extended elongated bars having formed at each end thereof and in their outer faces channel shaped seats 10. In each seat 10 is loosely journaled a pinion 11. There are two of these pinions 11 for each guide head 9, and they are located one above and the other below the tubular bar 7. Each pair of pinions l1 meshes with a vertically extended rack 12 that extends parallel with the adjacent vertical edge of the window shade 4. The racks 12 are, as shown, preferably counter sunk in the inner faces of the window casing 2 and are rigidly secured thereto.

To positively lock the free ends of the window shade 4 to the racks 12 in different set adjustments, at will, I mount a pair of reversely acting plunger rods 13 in the tubular bar 7. These plunger rods 13 are placed end to end in the bar 7 with their outer ends arranged to work through the ends thereof. \Vedge shaped. heads 14 are formed on the outer ends of the plunger rods 13 and are adapted to project between the teeth of the racks 12. A coiled spring 15 is telescoped onto each plunger rod 13. The inner ends of the said spring 15 are anchored to the plunger rods 13 and their outer ends are anchored to the ends of the bar 7 and yieldingly hold the heads 14 in engagement with the teeth of the racks 12. At their inner ends, the plunger rods 13 are longitudinally reduced and the reduced ends thereof are overlapped and longitudinally spaced apart,

one from the other, as shown in Fig. 2. Rack teeth 16 are formed in the inner faces of the reduced ends of the rods 13 and mesh with a pinion 17 located intermediately therebetween. The pinion 17 is loosely journaled to the bar 7 and one end thereof projects through said bar and has rigidly secured thereto a finger piece 18.

As is evident, by rotating the finger piece 18 in the proper direction, the plunger head 14 may be withdrawn from engagement with the teeth of the rack 12 against the tension of the springs 15. When the plunger heads 14 are out of engagement with the teeth of the racks 12, the window shade 4 may be either raised or lowered, as desired. The spring actuated roller 5 always keeps the window shade 4 stretched tight. As soon as the finger piece lSis released from the hand, the plunger heads 14 will be forced into engagement with the racks 12, under the action of the springs 15, thereby positively locking the window shade wherever set against the tension of the spring roller 5 and against any tendency to work up, caused by the ar oi the car.

ll hat I claim is l. T he combination with a window shade and a cooperating mechanically wound roller, of a bar secured to the free end of said sh ade, racks extending in the direction of the travel of said shade and being fixed with respect thereto, guide heads secured to the ends oi said bar, pinions carried by said guide heads and located in advance of the bar in either direction of the travel thereof, and means for holding said shade in diiierent set adjustments at will.

2. The combination with a window shade and a cooperating mechanically wound roller, 01 a tubular bar secured to the free end of said shade, a pair of reversely acting plunger-s mounted in said bar, racks extending in the direction of the travel of said shade and being fixed with respect thereto, yielding means for holding said plungers interlocked with said racks, means for releasing said plungers from engagement with said racks at will, and guide heads secured to said bar and cooperating with said racks.

3. The combination with a window shade and a cooperating mechanically wound roller, of a tubular bar secured to the free 'end of said shade, a pair of reversely acting plungers mounted in said bar, racksextending in the direction of the travel of said shade and being fixed with respect thereto, yielding means for holding said plungers interlocked with said racks, means for re leasing said plungers from engagement with said racks, at will, guide heads secured to said bar and through which said plungers work, and pinions carried by said guide heads and meshing with said racks.

i. The combination with a window shade and a coiiperating mechanically wound roller, of a tubular bar secured to the free end of said shade, a pair of reversely acting plungers mounted in said bar, racks extending in the direction of the travel. of said shade and being fixed with respect thereto, yielding means for holding said plungers interlocked with said racks, means for re leasing said plungers from engagement with said racks, at will, guide heads intermediately secured to the ends of said bar and through which said plunger-s work, and pinions carried by said guide heads, located on either side of said plungers and meshing with said racks.

In testimony whereof I aflix my signature in presence oi two witnesses.
